abbedissestue.

abbedisse + stue, first part from Old Norse abbadís, abbadissa (“abbess”), through Middle Low German abbadisse, from Medieval Latin abbātissa (“abbess, female head of an abbey”), from both Latin abbās, from Ancient Greek ἀββᾶς (abbâs), an alternative form of ἀββα (abba, “father, title of respect given to abbots”) from Aramaic אבא (’abbā, “father”), from Proto-Semitic *ʔabw- (“father”), from Proto-Afroasiatic *ʔab-, ultimately an onomatopoeic nursery word, and from -issa (“feminine noun-forming suffix”), from Ancient Greek -ισσα (-issa), likely from -ης (-ēs), from Proto-Indo-European *-ēs. Last part from Old Norse stofa, from the older form stufa, from Proto-West Germanic *stubu (“room, living room, heated room”).
